Description

Technical Field

[0001] The invention relates to the technical field of nursing pad production, in particular to a folding mechanism for nursing pad production and a use method thereof. Background Art

[0002] Nursing pads are disposable sanitary products made of PE film, non-woven fabrics, fluff pulp, polymers and other materials. They are mainly used in hospital surgery, gynecological examinations, maternal care, child care, paralyzed patients with incontinence, and women during menstruation. Nursing pads are produced continuously and finally cut, folded, and finally formed into the required shape on the production line. In the actual operation process of producing nursing pads, affected by the material of the nursing pads, the existing folding mechanism does not have a mechanism to clamp the nursing pads when folding the cut nursing pads. For the folding mechanism, when folding, the side of the nursing pad that has not been flipped may be affected by the flipping of the folding plate, which will push the nursing pad on the side that has not been flipped and folded to the flipping direction or the nursing pad may be offset, resulting in the movement of the nursing pad that has not been flipped after flipping and folding, resulting in wrinkles, affecting the flatness of the folding of the nursing pad. In order to ensure the folding quality of the nursing pad, personnel may need to remove the wrinkled nursing pad after folding and refold it, thereby increasing the workload of personnel and reducing the practicality of the folding mechanism.

[0003] To this end, the prior art solution (Announcement No.: CN 219688947 U) discloses a folding mechanism for producing nursing pads. After the nursing pad is straightened, the second motor is started to rotate the rotating rod, and the rotating rod then drives the flip plate to rotate and rotates and presses in the direction of the transmission plate. When the flip plate rotates, one side of the nursing pad between the two rotating rollers is pushed and pulled apart from the two rotating rollers, so that the flip plate flips and folds one side of the nursing pad, and through the clamping plate and the other side of the nursing pad, when one side of the nursing pad is flipped and folded, the other side will not be pushed to wrinkle or deflect, so there is no need for personnel to take it off and refold it, which reduces the burden on personnel and improves the practicality of the folding mechanism.

[0004] Although this technical solution can fold the nursing pad, due to different production requirements, the folding method of the nursing pad is also different, and it cannot meet different folding methods, which makes the use of this mechanism limited.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-11The folding mechanism for producing a nursing pad comprises a base 1, a base 2 is fixedly installed on the top of the base 1, an electric control box 3 is installed inside the front of the base 2, a main platform 4 is fixedly installed on the top of the base 2, longitudinal pushing structures are arranged on both sides of the main platform 4, a transverse pushing structure is installed inside the longitudinal pushing structure, and a limited position structure is also arranged inside the main platform 4. A bracket is fixedly installed on the back of the base 1, the bracket is L-shaped, and a first cylinder 5 is fixedly installed on the top, and a pressing plate 6 is connected to the output end of the first cylinder 5. A driving structure is arranged inside the base 1, and a longitudinal pushing structure that can be raised and lowered is arranged on both sides of the main platform 4, so that the two ends of the nursing pad can be pushed upward, and at the same time, a transverse pushing structure is arranged inside the longitudinal pushing structure, so that the two ends of the nursing pad pushed upward can be transversely folded, so that the nursing pad can be folded at both ends, or the nursing pad can be folded in half by controlling the longitudinal pushing structure on one side alone, so that the structure can realize a variety of folding methods for the nursing pad, which solves the problem that the folding method of the prior art is single and there are limitations in use.

[0023] In order to limit the position of the nursing pad when folding, to avoid the longitudinal and transverse push structures failing to fold according to the set folding distance, resulting in the incorrect folding position of the nursing pad, please refer to Figure 1-2 and Figure 8-11 , place the nursing pad flatly on the top of the main platform 4. In the initial state, the fourth cylinder 15 is in an extended state, and the limit plate 16 is located outside the main platform 4, and there is a gap between the main platform 4. After the nursing pad is placed, start the program pre-set by the PLC module, the fourth cylinder 15 contracts, and drives the L-shaped limit plate 16 to move toward the main platform 4 until the limit plate 16 is above the nursing pad. Since the thickness of the limit plate 16 is less than the gap between the accommodating groove and the side edge of the main platform 4, and there is a gap between the bottom surface and the top surface of the main platform 4, the limit plate 16 will not contact the nursing pad during the movement, so as not to push the nursing pad to move and affect the subsequent folding. After the limit plate 16 moves into place, the longitudinal pushing structure can be driven to fold the nursing pad. The limit plate 16 can cooperate with the top platform 12 in the longitudinal pushing structure so that the two ends of the nursing pad can be vertically erected, avoiding the problem that the nursing pad cannot be bent into place during the longitudinal pushing structure due to lack of limit, which is convenient for subsequent folding.

[0024] Among them, the edge of the side end of the limiting plate 16 close to the top platform 12 is parallel to the edge of the main platform 4, and a slot adapted to the same limiting plate 16 is opened. This structure can expand the width of the limiting plate 16. It only needs to insert the adapted limiting plate 16 into the slot and connect it. In conjunction with the subsequent driving structure, the pushing distance of the longitudinal pushing structure can be adjusted.

[0025] To achieve the push-fold function on both ends of the nursing pad, refer to Figure 1-2 and Figure 4-5After the limit plate 16 moves into place, the PLC module drives the second cylinder 11 to start, pushing the top platform 12 to move upward, and the top platform 12 pushes the two ends of the nursing pad to bend upward. With the cooperation of the limit plate 16, the two ends of the nursing pad are vertical, which is convenient for subsequent folding.

[0026] Among them, the top platform 12 is symmetrically arranged on both sides of the main platform 4, and the height is consistent with the height of the main platform 4, so that the nursing pad can be placed flat on the main platform 4. The top edge of the top platform 12 facing the main platform 4 is set to an arc shape, which can protect the nursing pad when the two ends of the nursing pad are pushed to bend, avoiding damage to the nursing pad, and also can smoothly push the nursing pad to bend.

[0027] To achieve the function of folding the nursing pad after bending both ends, please refer to Figure 1 , Figure 4 and Figure 6-7 After the longitudinal pushing structure bends the two ends of the nursing pad into a vertical shape, the PLC module drives the third cylinder 13 to extend, pushes the push plate 14 to extend to the outside of the top platform 12, pushes the two sides of the nursing pad in a vertical state toward the center of the nursing pad, and folds it in parallel with the top surface of the nursing pad, thereby completing the folding of the two ends of the nursing pad. After folding, the fourth cylinder 15 is controlled to shrink and reset, and the limit plate 16 is out of contact with the nursing pad to avoid the thickness of the limit plate 16 affecting the molding of the nursing pad during the subsequent folding and molding of the nursing pad.

[0028] Among them, a receiving groove of the same size as the push plate 14 is opened on the side of the top platform 12 facing the main platform 4, which is used to accommodate the push plate 14 to avoid interference with the edge of the main platform 4 during the rising process of the top platform 12, resulting in damage. The height of the receiving groove is set higher than the side edge of the main platform 4 when the third cylinder 13 is extended to the limit, and a gap is set between the side edge of the main platform 4, which can leave a thickness space for the nursing pad so that the nursing pad can be folded. The bottom edge of the push plate 14 close to the main platform 4 is set to an arc shape, which can protect the nursing pad from being scratched by the push plate 14 when the nursing pad is pushed to fold.

[0029] To achieve the function of forming the folded nursing pad, please refer to Figure 1-2 After the lateral pushing structure folds the two ends of the nursing pad into parallel, the PLC module drives the third cylinder 13 to contract and reset, while driving the first cylinder 5 to extend. The first cylinder 5 pushes the pressing plate 6 to move downward until it contacts the nursing pad and flattens the nursing pad.

[0030] To adjust the distance between the longitudinal push structure and the main platform 4 to accommodate the folding of nursing pads of different sizes, please refer to Figure 1-3 and Figure 5When it is necessary to fold nursing pads of different specifications, the dual-axis motor 7 is driven, and its output end drives the threaded rods 8 at both ends to rotate, and the inverted T-shaped slider 9 threadedly connected to the outer wall of the threaded rod 8 slides in the slide groove inside the base 1, and at the same time drives the L-shaped moving plate 10 fixedly connected to the slider 9 to move horizontally on the base 1, and drives the longitudinal pushing structure fixedly installed with the top of the moving plate 10 to move horizontally, thereby realizing the adjustment of the distance between the longitudinal pushing structure and the main platform 4, so that the present invention can adapt to the folding of nursing pads of different sizes, and improves applicability.

[0031] The height of the top surface of the movable plate 10 is parallel to the top surface of the base 1 , which can ensure that the top platform 12 maintains the same height as the main platform 4 in the retracted state to prevent misalignment.

[0032] Among them, the first cylinder 5, the second cylinder 11, the third cylinder 13 and the fourth cylinder 15 are controlled by the PLC module inside the electric control box 3 and are electrically connected to the PLC module. The above components are all existing technologies on the market. The PLC module drives the actions of each component by writing a program, which will not be elaborated here.

[0033] The present invention uses the following steps: Step 1: Place the nursing pad to be folded on the top of the main table 4. In the initial state, the limit plate 16 is opened outward and the fourth cylinder 15 is in an extended state. After placement, start the program pre-set by the PLC module, and the fourth cylinder 15 contracts, driving the limit plate 16 to move toward the main table 4 until the limit plate 16 is above the nursing pad. Step 2: In the initial state, the main platform 4 is parallel to the top platform 12. After the limit plate 16 moves into place, the second cylinder 11 is started to push the top platform 12 upward, and the top platform 12 pushes the two ends of the nursing pad to fold upward; Step 3: When the two ends of the nursing pad are in a vertical state with the nursing pad, the third cylinder 13 is started, the third cylinder 13 is extended, and the push plate 14 is pushed outward from the top platform 12, and the two sides of the nursing pad in a vertical state are pushed toward the center of the nursing pad, and the nursing pad is folded in parallel with the top surface of the nursing pad. After folding, the fourth cylinder 15 is controlled to retract and reset, and the limit plate 16 is out of contact with the nursing pad; Step 4: After the two ends of the nursing pad are folded in half, the PLC module drives the third cylinder 13 to contract and reset, and at the same time, starts the first cylinder 5 to push the pressing plate 6 on the top of the main platform 4 to move downward until the folded nursing pad is pressed tightly to form it. After forming, all parts are reset, the folded nursing pad is taken away, and the folding process is completed.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
